I do use a USB sound card with it, a Behringer 302USB, it even powers
the sound card, which also powers the phantom power needed for my mic.
I get a good clear recordings, but for now I can't figure out
why the output has so much noise (sounds like it's picking some
interferences or clock or ...?). But the drivers are here yes, but
maybe not for all the cards :)
